Detailed explanation-1: -In contrast, ectotherms rely on behavior to regulate their body temperature. They must move their bodies into the shade or sun to cool down or warm up. This requires less energy than constant metabolic regulation.
Detailed explanation-2: -The word “ectotherm” refers to animals that generally have a body temperature comparable to their surrounding environment. They cannot internally regulate their body temperature. People often refer to them as “cold-blooded”, but this term tends to misdirect people more often than not.
Detailed explanation-3: -Mechanisms of thermoregulation Endotherms, such as birds and mammals, use metabolic heat to maintain a stable internal temperature, often one different from the environment. Ectotherms, like lizards and snakes, do not use metabolic heat to maintain their body temperature but take on the temperature of the environment.
Detailed explanation-4: -Answer and Explanation: The correct statement about ectotherms is D. ectotherms use more energy for reproduction than for heat production. Since ectotherms do not use a lot of energy to maintain a stable internal body temperature, they will allocate more energy for reproduction than endotherms.
